【発明の詳細な説明】
産業上の利用分野
本発明は鉛蓄電池の保存特性の向上に関するものである
。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to improving the storage characteristics of lead-acid batteries.
従来の技術
従来の鉛蓄電池用負極板は、鉛又は鉛合金を鋳造あるい
はエキスバンド加工などに上り集電体格子を作成し、こ
の集電体に主成分が酸化鉛よりなる活物質原料を塗着、
乾燥しついで化成して極板としていた。Conventional technology A conventional negative electrode plate for a lead-acid battery is produced by casting or expanding lead or a lead alloy to create a current collector grid, and then coating this current collector with an active material whose main component is lead oxide. Arrival,
After drying, it was chemically converted into electrode plates.
ここでの活物質原料は酸化鉛を主体とする鉛粉と硫酸と
水を混合し練合したもので、機械的強度を改善するため
に耐酸性の合成樹脂繊維を添加したものである。The active material raw material here is a mixture of lead powder, mainly lead oxide, sulfuric acid, and water, and acid-resistant synthetic resin fibers are added to improve mechanical strength.
またその他の添加剤として、硫酸バリウム、リプニンス
ルホン酸ナトリウムなどがあるのみである。Other additives include barium sulfate and sodium lipninsulfonate.
発明が解決しようとする問題点
しかし、これらの添加剤のみでは近年発展の著しい密閉
形の鉛蓄電池、すなわち電解液量が少なく制限された電
池に要求される負極板の親水性および吸液性は不充分で
あった。Problems to be Solved by the Invention However, these additives alone cannot meet the hydrophilicity and liquid absorption properties of the negative electrode plate required for sealed lead-acid batteries, which have been rapidly developed in recent years, that is, batteries with a small and limited amount of electrolyte. It was insufficient.
またセパレータに対しても特に負極板に電解液が供給さ
れやすい特性を付与したものはなかった。In addition, there has been no separator that has characteristics that allow the electrolyte to be easily supplied to the negative electrode plate.
問題点を解決するだめの手段

合物を塗布、充填してセパレータとの接触率の向上を図
り、負極板の電解液充填率の低下による問題点を解決し
たことを特徴とした鉛蓄電池である。Means to Solve the Problems The present invention provides negative electrode active material paste with a certain amount of either a predetermined liquid-absorbing fine powder, a hydrophilic fine powder, or a mixture thereof, and this additive. A negative electrode plate with a certain amount of conductive fine powder added to compensate for the conductivity between particles and at the interface between the active material and the lattice to improve hydrophilicity and liquid absorption, and the separator surface in contact with this negative electrode plate. By coating and filling either hydrophilic fine powder, liquid-absorbing fine powder, or a mixture thereof into the electrode, the contact rate with the separator was improved, and the problem caused by the decrease in the electrolyte filling rate of the negative electrode plate was solved. This is a lead-acid battery with the following characteristics.
作用
本発明による鉛蓄電池は、負極板の吸液性、親水性が向
上するとともに、電解液を最も多く含むセパレータとの
接触面積が向上するため、長期保存中に電解液中の水分

定量より減少した場合においてもセパレータから電解液
の供給を受けやすいため、長期保存後の問題点の1つで
ある負極板中の電解液の充填率の低下による容量の低下
を抑制することが出来る。In the lead-acid battery according to the present invention, the liquid absorbency and hydrophilicity of the negative electrode plate are improved, and the contact area with the separator containing the largest amount of electrolyte is improved, so that water in the electrolyte is absorbed into the battery during long-term storage. Even if the amount of electrolyte decreases below a predetermined amount due to diffusion through the wall into the atmosphere, it is easy to receive electrolyte from the separator, which is one of the problems after long-term storage. It is possible to suppress a decrease in capacity due to a decrease in filling rate.
